[PySide] modify member assignment?

I have a struct with a double member variable. Now, normally, from 
Python I would not be allowed to assign None to this member, but I would 
like to allow this (there is a special value that means 'invalid' on the 
C++ side that I would like to assign if in Python the user assigns 
None). Is this possible?

I think I can figure out the code injection to handle None, but I'm not 
sure how (or if it is possible) to declare a member assignment on which 
to hang the injection.
